- LOCK-STRIKE.

Specification of Letters Patent- Patnted Dec, 18, .191'7,

Application'filed August 16, 1917. Serial No. 186,591.

has for its object the provision of means whereby the bolt and latchengaging member may be ad usted to compensate for sagging or shrinkingof the door or the doorframe without removing the lock strike from thedoor amb. A secondary object of the 1nvention is to provide a'devlce forthe stated purpose which may be readily applied to a door jamb andwhich, when applied, may be adjusted by an unskilled person withoutdetracting from the neat appearance of the door or the door-frame.

The invention is illustrated in the accompanying drawings, in whichFigure 1 is an elevation of a portion of a door jamb with my improvedstrike applied thereto;

Fig. 2 is a sectional view taken in a plane immediately in rear of thebase plate of the lock strike;

Fig. 3 is a longitudinal transverse section of the complete device inposition-on the door j amb;

Fig. 4: is a perspective view of the face plate or bolt engaging andholding member;

Fig. 5 is a perspective view of the base plate.

In carrying out my invention, I form a recess 1 in the door j amb 2 forthe reception of the strike in the usual manner. In the base of therecess 1, I form a central seat 3 and from the ends of said central seatlongitudinal grooves 4 extend to the ends of the recess 1. At the endsof said grooves 1, sockets or cavities 5 are provided for a purposewhich will presently appear. Extending laterally from the side walls ofthe seat 3 are recesses or grooves 6 which extend to the side walls ofthe recess 1 and at the ends of said grooves are sockets or cavities 7similar to the sockets or cavities 5. The lock strike comprises a baseplate 8 adapted to be secured in the recess 1 and a face plate 9 adaptedto bear against the outer surface of the base plate and provided withthe usual lip or projection 10 against which the latch may strike as thedoor is closed. The base plate 8 is of the proper dimensions and form tofit'snugly withinjthe recess 1 and at its cornersor at-other convenientpointsis provided with openings 11 through which screws or otherfastening devices 12 may be inserted into the door jamb to "secure theplate in place. The base plate isconstructed with a longitudinal slot oropening. 13 which is approximately of the same dimensions as the seat 3formed in the door jamb and at the ends and sides of the base plate,lugs 14 .are'formedon its rear surface at its edges to enterthe'grooves& and 6 in the door jamb. These lugs and the correspond ing groovesshouldbe of such dimensions that the lugs will fit easily but closelywithr in the grooves so that the engagement of the lugs and grooves willaid in retaining the base plate in its proper position. The lugs, areperforated and the perforations are internally threaded as-will bereadily understood upon reference to the drawings. Otherv lugs 14:, theopenings through which are unthreaded, are provided between theends ofthe slot 18 and the end lugs 14:. The face plate 9 is provided withopenings or slots 15 for the reception of the ends of the bolts andlatch and on its rear side around the edges of said openings or slotsare ribs or flanges 16 which are adaptedto extend into the seat 3 andare provided with longitudinal slots 17 having beveled Walls, as

shown most clearly in Figs. 2 and 3. Re-

secure the face plate upon the base plate, the

end screws 18 being longer than the side screws and having theirintermediate unthreaded portions passing through the lugs 1 1 and beingthereby held against bending. The beveled heads of the screws by theirengagement with the beveled walls of the slots will secure the faceplate so that it can not drop away from the base plate or the door jambbut will permit adjustment of the face plate relative to the base plateand the door jamb both longitudinally and transversely. The ends of thescrews in extreme positions of the face plate will extend into thesockets 5 and 7 so that a wide range of adjustment will be permitted.

From the foregoing description, taken in connection with theaccompanying drawings,

it will be readily seen that I have provided a very simple, inexpensiveand eflicient device whereby the lock strike may be easilyad-' the lock.The seat 3 in the door jamb and the slot or opening 13 in the base platewill be large enough to accommodate the ends of the latch and the boltunder all conditions and the outside dimensions of the face plate shouldbe such that said seat and opening will be covered notwithstanding theextreme position in which the face plate may be set. As the only toolnecessary to effect the adjustment of the device is a screw driver itwill be obvious that the services of a skilled workman will not. beneeded. WVhen the device is in position the appearance of the door isneat and sightly so that the use of the device will be nnobjectionableand the adjusting screws by which the face plate is retained in positionupon the base plate will all be hidden, and the strike will differ verylittle in appearance from the ordinary lock strike now in common use. i

Having thus described the invention, what is claimed as new is:

l. A lock strike comprising a base plate, a face plate fitting againstthe outer surface of the base plate and means carried by therear side ofthe face plate and engaging the rear side of the base plate to securethe plates in a set position, said means being covered by the plates.

2. A lock strike comprising a base plate provided with a bolt receivingopening and having threaded lugs onits rear side, a face plate providedwith a bolt opening and having outstanding longitudinally slotted ribson its rear side, and retaining devices inserted through said ribs topermit relative movement of the face plate and engaging the lugs on thebase plate to secure the plates together.

In testimony whereof I afiix my signature.

WILLIAM IV. PILCHARD.
